Victron MultiPlus-II 12/3000 120V 50A Inverter Charger | 3000VA Pure Sine Wave

Victron MultiPlus-II 12/3000 120V 50A Inverter Charger

The Victron MultiPlus-II 12/3000 120V is a powerful all-in-one pure sine wave inverter and battery charger designed for off-grid, marine, RV, backup power, and energy storage applications. Combining the proven features of the MultiPlus and MultiGrid series, this advanced inverter charger delivers reliable AC power, intelligent battery charging, and seamless system integration.

Advanced PowerAssist & PowerControl Technology

The MultiPlus-II prevents overload situations when using limited AC power sources such as generators, shore power, or grid connections. PowerControl automatically adjusts battery charging to prevent excessive demand, while PowerAssist supplements available AC power with energy from the battery when additional power is required.

Reliable UPS Backup Power

With built-in uninterruptible power supply functionality, the MultiPlus-II automatically switches to inverter mode during a grid, generator, or shore power failure. The ultra-fast transfer time keeps sensitive electronics, computers, and equipment running without interruption.

Energy Storage System Compatible

The Victron MultiPlus-II is designed as a core component for advanced energy storage systems (ESS). It works seamlessly with Victron solar charge controllers, lithium battery systems, and grid-connected solar applications for maximum energy independence.

Parallel, Split Phase & Three Phase Operation

Multiple MultiPlus-II units can be connected together to increase available power output. Systems can be configured for parallel operation, split-phase setups, and three-phase applications, making it ideal for residential backup power, commercial installations, and large off-grid systems.

Remote Monitoring & Control

When paired with a Victron GX device, users can monitor and control their entire power system locally or remotely. Adjust settings, monitor battery performance, view system status, and manage connected equipment from a smartphone, tablet, or computer.
